Hi, all,
Notwithstanding my history of GUI rejection, I'm trying to make peace
with the SAGE notebook, which I think is pretty neat. The latest
incarnation (I'm using 2.7.1, on Mac OS X, with Safari) looks pretty
good.
However, I run into odd behavior that makes me think that I'm just
inept. I'm hoping someone can shed some light for me.
Here's an example.
I enter the following:
{{id=0|
def CompSum(a,b):
return a+b
}}}
{{{id=1|
CompSum(3,4)
///
7
}}}
{{{id=3|
2+2
///
4
}}}
{{{id=4|
Q.<i,j,k>=QuaternionAlgebra(QQ,-3,4)
}}}
{{{id=12|
Q
///
Quaternion algebra with generators (i, j, k) over Rational Field
}}}
{{{id=10|
Q.discriminant()
///
2304
}}}
and so far, so good. Then I do
{{{id=11|
Q.is_commutative()
}}}
{{{id=14|
}}}
I expect something printed, but nothing shows (and the 'id=14' cell
is "empty"). Even more puzzling
is
{{{id=15|
2+2
}}}
{{{id=16|
}}}
This seems quite repeatable. The Log verifies the above.
If I use SAGE from the shell, and repeat the above, I see what I
would expect (False and 2+2 for the last two). The 'server' window
(from which I run "sage -notebook") is littered with entries like
2007/07/29 16:01 -0700 [HTTPChannel,5,127.0.0.1] Quitting
ignored worksheet process for 'My First Try'.
These show up for each of the above.
Perplexedly,
Justin
